用角度过滤对象

Question

I am trying to filter an object in angular controller. I always get undefined as a result in my variable and cant figure out why. I made a screenshot of my console. where you can see the object and the filter function. What am i doing wrong?

OK here is the main part of the function. Am getting back undefined, so it have to do something with the way am using the filter?:

this.update_lead_status = function (lead, sts) {

            this.status = $filter('filter')(leads.leads_status, { ls_id: 3 });

        };

The json object which is provided by a service:

leads.leads_status [
{ls_id: 1, ls_class: 'lost', ls_name: 'Status1'},
{ls_id: 2, ls_class: 'lost2', ls_name: 'Status2'}
]

I am trying to get back the object item based on the ls_id and asign the variables one by one to my scope! Thanks

Answer 1

I had to add a [0] to the end of my filter function, like this:

var status = $filter('filter')(leads.leads_status, { ls_id: sts })[0];

Now it works fine for me!
